我怎样才能mod_rewrite的，并保持查询字符串？ [英] How can I mod_rewrite and keep query strings?

问题描述

我要mod_rewrite的一个URL到另一个页面，后来我也想添加任何查询字符串是preserved。

I want to mod_rewrite a URL to another page, but then I also want any query strings added to be preserved.

RewriteEngine On

#enforce trailing slashes
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !#
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://localhost/siteroot/$1/ [L,R=301]

RewriteRule ^apps/([A-Za-z0-9-_]+)/?$ index.php&app=$1

因此​​，如果用户访问应用程序/ APP1 / ，的index.php？应用= APP1 显示。 不过，我希望能够以preserve可选的查询字符串，使来访应用程序/ APP1 /？变量= X 返回的index.php ？应用程序= APP1和放大器;变量= X

So if a user visits apps/app1/, index.php?app=app1 is shown. However, I want to be able to preserve optional query strings, so that visiting apps/app1/?variable=x returns index.php?app=app1&variable=x.

什么的mod_rewrite规则/条件会做到这一点？

What mod_rewrite rule/condition would make this happen?

推荐答案

您需要添加的 [QSA] 标志（查询字符串附加）

You need to add the [QSA] flag ("query string append")

RewriteRule ^apps/([A-Za-z0-9-_]+)/?$ index.php&app=$1 [L,QSA]

有关301页面重定向与 [R] 标记，而不是内部重写像这样的，查询字符串将自动添加。但是，你必须强迫它 [QSA] 的内部重写。

For page 301 redirects with the [R] flag as opposed to internal rewrites like this one, the query string is automatically appended. However, you must force it with [QSA] for the internal rewrite.
